  • What is UNIX? (was: Hot T

    From Dumas Walker@VERT/CAPCITY2 to FUSION on Fri Oct 3 10:17:35 2025
    AIX, HP-UX, macOS, Xinuos, z/OS (see "Single UNIX Specification", wikipedia)

    since i suspect there aren't users of 4 of those on dovenet (the most likely being perhaps AIX), might i suggest this echo be used only for macOS?

    I was a professional user of z/OS until recently. ;) I used several
    console utilities that "sat on top of" it, but I only got down to using
    things from the *nix command line once or twice.

    That list reminded me of some of the "weird" UNIXes out there, like
    Primos - it ran on top of PRIME/OS on big CDC iron. That was the
    closest my college came to UNIX, it was great for teaching shell
    scripts and BASH to tons of college students, but you couldn't develop
    on it.

    This was the late '80s. After the weed-out CS classes and a class in
    assembler on a VAX 11/750, we did all of our compiling on our own PCs.
    Most people used Turbo C, but I was the oddball (go figure?), I had a
    deal from the bookstore on Microsoft QuickC, but ended up using EMACS
    as an IDE with Mark Williams C, with a BASH shell and *nix* commands
    for DOS.

    I did not realize they had UNIX layers on mainframes back then, but it
    makes sense to do so.

    I used a VAX during college, but more as a "user" and didn't learn much, if anything, about the underlying OS commands or shell. The programming
    classes I took were both PC-based... BASIC and PASCAL. The languages that
    had more practical application... Assembler, FORTRAN, COBOL... were
    reserved for students in the engineering school.

    I also didn't realize they had BASH shells and *nix commands for DOS back
    then.

    Luckily, there were a few places in the 1990s where one could get a job
    with a related degree and then get OTJ training. That is where I learned
    most of what I know and used professionally.

    Do you remember if they ran VMS or Ultrix?
